Band members Una Healy (31), Frankie Sandford (24) , Mollie King (25), Vanessa White (23) and Rochelle Humes (23) posed for the cameras and chatted about their upcoming US reality show Chasing The Saturdays.
With their hair back combed, plenty of smoky eye makeup and wearing racy and lacy red and black ensembles the girls pouted their way through the photoshoot -- a further attempt to help their bid to crack the US market.
In one shot, Frankie flashes her black bra in a sheer floor-length red lace dress.
In another Mollie is seen leaning against a wall and staring provocatively at the camera in a fitted black dress with laser cutout detail and an ostrich feather fishtail kick.
Co Tipperary beauty Una went for a rock chick Little Black Dress.
A fitted waist and full skirt emphasised her petite frame while leather detailing gave the look that added edge.
Una teamed her dress with a pair of statement purple ankle boots.
Mum-to-be Rochelle is glowing in a black lace dress.
Meanwhile Vanessa showed off her curves in a floor length gown with fitted bodice.
The Saturdays are well on their way to Stateside domination. In the run-up to their show they've attended every red carpet event in LA and NYC.
They chatted with Hollywood A-Listers at the Golden Globes, have performed at the Highline Ballroom in New York, faced comedienne Joan Rivers wrath on hugely rated E! show Fashion Police, shared a laugh backstage with 50 Cent at NBC studios, and appeared on the hugely popular Chelsea Lately Show.
Mum-of-one Una said she was in a state of shock when she saw singer and actress Jennifer Lopez at the Globes.
"Starstruck wasn't even close to the expression on our faces when J-Lo walked past us in the corridor last night," she told her twitter fans.
"Her bum is the best."
Filmed last summer, The Saturdays promise the show will be packed full of drama and are feeling nervous but excited about the launch.
The girls said: "We are extremely excited and a little bit nervous because it's going to be the first time people are going to be seeing our personal lives.
"It's going to be weird, but hopefully everyone will like it, and like us!"
Una left husband rugby player Ben Foden behind when she travelled to LA last year with their daughter Aoife Belle for filming.
The Thurles native found the time apart from her new husband a challenge.
"It's very difficult being away from my husband because we were newlyweds when we came out to Los Angeles.
"He's very understanding and his job as a professional rugby player takes him away a lot, so it kind of keeps things fresh," she said.
